Description

7901612-7 2 The invention will be described in more detail below with reference to the accompanying drawings. Drawing 1 shows a perspective view of a preferred embodiment of the invention. Drawing 2 shows the cutting device.

In the figure, a rotary cutting device is generally denoted by the reference numeral 1, one after the rotary cutting device 1 located from this downwardly sliding slide plane is denoted by the reference numeral 2 and a cassette adapted to the sliding plane 2 is generally denoted by the reference numeral 3.

The cassette has been divided by means of partitions 4 into intermediate spaces 5, the length of which corresponds to the length and width of the cut strips, again being determined on the basis of the width of the cut strips. The upper edge of the partition walls 4 is located above the extension of the sliding plane 2 and the partition walls 4 continue out on the sliding plane 2 in the form of vertical longitudinal guide walls 6, the upper end of which slopes obliquely with the upper edge 7 of the sliding plane 2.

The rotary cutting device 1 comprises two shafts 8 and 9 adapted horizontally one above the other. On both shafts are at equally axially spaced apart rotating bit 10 so that the bit 10 on the upper shaft 8 is slightly overlapping with the opposite bits 10 on the lower shaft 9, the shafts 8 and 9 being adapted to rotate in opposite directions in order to cut a disc blank fed between the bits 10 on each shaft 8 and 9 into unidirectional adjacent strips and to discharge the strips on the inclined sliding plane 2 between the guide walls 6.

After the rotary cutting device 1, each cut strip falls down on a lateral displacement plate, which plates extend in the longitudinal direction from the rotary cutting device 11 substantially halfway into the inclined sliding plane 2. Laterally, each lateral displacement plate 11 extends from the angle between the guide wall. 6 and the sliding plane 2 obliquely upwards over the upper edge of the adjacent guide wall 6 and partly above the following guide wall gaps. Since the upper ends of the guide walls 6 are chamfered, the inclination of the side displacement plates 11 will gradually increase in the direction of their drain edge 12.

The task of the lateral displacement plates is on the one hand to keep the edges of the adjacent strips separated from each other so that the strips do not get stuck in each other, and on the other hand to displace the strips laterally so that each strip is guided into the corresponding PQOR Qia-Ifr 7901612-7 3 the spaces of the partition wall and from there further on each other into the space 5. The strips thus slide by their own weight to the side from each other and at the same time forward each into their own space 5 in the cassette 3 The lateral displacement is necessary already for the reason that the division between the gaps 5 in the cassette 3 due to the space required by the partition walls is greater than the division between the bits 10 of the rotary cutting device 1. For this reason the lateral displacement plates 11 must be adapted slightly laterally and so that the degree of overlap grows laterally (1 figure to the left).

The uneven edge strips fall after the cut over the outer guide walls of the sliding plane 2 down on both sides of the sliding plane. For one edge strip, a disc 15 directed upwards towards the sliding surface 2 extends from the corresponding outermost guide wall to the side, along which edge edges can slide to the side on the same.

In order to feed the disc blank and to guide the strips, there is on the side of the rotating bit 10 of the upper shaft 8 a circumferential surface 13 of smaller diameter, which together with the opposite rotating bit 10 at a corresponding place of the lower shaft 9 forms a press. pinch for the substance. In addition, the circumferential surface 13 of both rotating bites 10 is coated with resilient material 14 to provide press contact with the disc without damaging the disc.

The inclination of the side displacement plates 11 and the sliding plane 2 is chosen so that the cut strips by means of the kinetic energy they receive from the rotary cutting device and by gravity themselves slide and fall into the cassette 3. The feed speed should of course be adjusted so that the cut strips slide away before the following strips appear on the slide 2.

The end wall of the cassette 3 is also openable, so that the stacks of strips in the intermediate spaces 5 can be removed from the cassette 3 and moved to the starting plate machine in order to bend the strips and fasten them in the starting plates. Alternatively, the entire cassette can be transferred to? the starting plate machine.

Claims (5)

7901612-7 4 PATENT CLAIMS Device for stacking strips cut by a board blank on each other in adjacent spaces (5) separated by partitions (4), the cut strips being discharged in the feeding direction on a downwardly sloping slide plane (2), which in substantially the same longitudinal vertical plane as the adjacent walls (4) of said adjacent spaces (5) have guide walls (6), the upper end of which advantageously coincides obliquely with the inclined plane (2), in order to receive the cut strips and guiding them into their respective spaces (5), characterized d. by slightly forward and downwardly extending in the feeding direction, as well as laterally inclined side displacement plates (11), which laterally extend from the space between the two adjacent guide walls (6) over one guide wall at most up to a longitudinal vertical plane through the point of intersection of one edge of the strip coming on the side displacement plate (11) and through a longitudinal vertical plane passing at least through the midpoint between the points of intersection of the edges of said strip, in order to tilt the cut strips and to cause the downwardly facing edge to slide along the adjacent guide wall (6) so that the upper side edge can fall down between the guide walls (6) before the strip falls into the space (5). Device according to claim 1, characterized in that the lower edge of the lateral displacement plates (11) joins the adjacent guide wall (6) and preferably simultaneously with the inclined plane (2). Device according to claim 1 or 2, characterized in that the length of the part of the guide walls (6) lying after the lateral displacement plates (11) is at least as large as the length of the cut strips. Device according to one of Claims 1 to 3, characterized in that the length of the side displacement plates (11) is at least equal to the length of the strips to be cut. Device according to one of Claims 1 to 4, characterized in that the guide walls (6) form a uniform smooth wall together with the corresponding partitions (4) of the spaces (5).
